BUNCH-BUILD Application filed .Tune 24, 1920. Serial No. 891,381.

To all whom it may concern:

Be it known that we, Jnssn L. LYLE and Josnrn FRANK BROOM, citizens of the United States, residing at Danville -in the county of Pittsylvania, State of Virginia, have invented a new and useful Bunch- Builder, of which the following is a specification.

This invention relates to bunch builders utilized for controlling the quantity of yarn left on quills from automatic looms. One of the objects of the inventlon is to reduce waste of yarn b insuring the proper construction of a s ort bunch of yarn at the base of the quill instead of allqwing the spinning frame to build the yarn pnto the quill with the full stroke from the the operation.

A further object is to roy de a bunch builder which can be applied to any splnning frame making filling for automatlc looms and which device has improved means for automatically controlling the length and depth of the bunch.

Another object is to provlde an improved means for changing the ring-rail connection from the bunch builder chain to the main builder chain.

A still further object is to provide a simple and compact structure capable of unnute adjustment and having its wearlng parts strong and durable.

With the foregoing and other ob ects in View, which will appear as the descrlptlon proceeds, the invention resides in the combination and arrangement-of parts and in the details of construction hereinafter destart of scribed and claimed, it being understood reference 1 designates a main bearing axle which serves to connect the present improvements with the base of a spinning frame, holding the mechanism in such pos1- are suitably connected.

mounted on a bracket 28 extendin tion that the eccentric (not shown) and which is mounted on a shaft of the spinning frame will come into contact with a roller 2 pro ecting laterally from the body P01? t1on 3 of the device and; journaled'ln a bracket 4. The eccentric ofthe spinning frame and which is above referred. to is adapted, bvenga'ging the roller 2, to impart an oscillating motion to the body 3 and the parts connected thereto-in a vertical plane about the axis of the shaft or axle 1. An arm 5 is extended from the body 3 of the machine and carries an adjustable counterbalance 6' whereby the machine is held in proper balance during the oscillat1on mentioned.

, 'A take-up rod 7 is fastened by means of a' bracket 8 and bolt 9 to a stationary part of the spinning frame (not shown) and this ed for oscillation on a longitudinal shaft 13. This shaft is j ournaled in suitable bearings 14 extending from the body 3 and is provided, near one end, with a worm 15 while secured tothe other end portion of the shaft is a ratchet wheel 16. A pawl 17 is pivotally mounted on the arm 12 and is provided with a wei hted arm 18 which serves to hold the paw normally in engagement with the ratchet wheel.

The worm 15 constantly meshes with a worm gear 19 which is formed with or connected to the driver 20 of the main builder chain 21 and also to the driver 22 of the bunch builder chain 23. These drivers can be in the form of drums to which the chains A trip 24 is pivotally 25 extending from the body 3 and has a longitudinally slotted arm 26 in which is adjust-ably mounted one end 'of a connecting rod 27 pivotally attached to a radial arm from the driver or drum 22. The trip 24 as an inclined face 29 adapted to be engaged by a trip release 30. A roller 31 is adjust-ably mounted in a slot 32 and is engaged by the chain 23, this roller being 'provlded for regulating the length of the bunch.

When the machine is set in motion the rod is connected by a turn bucklelO to a I release 30 engages the inclined face 29. As

the chain drivers 20 and 22 are turned in a clockwise direction by the motion of the ratchet 16 and the worm 15 the trip 24 is swun to the right by meaiis ofa connectingrod 2 The machine isso adjusted that the trip moves just far enough to disen age the release 30 when the desired bunch as been built on the base of the quill. The bunch builder chain 23 is connected to the ringrail (not shown) of the spinning frame and imparts a short stroke, gradually raising the ring-rail until the trip 24 is re eased. The main builder-chain 21 is also connected to the ring-rail and is engaged by the small driver 20 in such a manner that it releases the chain 21 more slowly than the chain 23. Chain 21 is so adjusted that it becomes ri ht at the instant that chain 23 releases. T us a longer stroke is imparted to the ring-rail and it is gradually lifted until the quil are filled.

The take-up rod 7 can be adjusted to different lengths by means of the turn buckle l0 and, therefore, the relative speed of the worm shaft to that of the spinning frame can be controlled. This allows the quills to be filled with {yarn to any desired depth. As the roller 31 is adjustable longitudinally within its pivoted supportin arm 33 in which the slot 32 is formed, t e bunch can be built of any desirecllength. The slot in the trip 24 allows the connecting rod to be adjusted relative to said trip 24 so as to cause the trip to release at a predetermined time during the operation of the device. Thus the depth of the bunch can be regulated.

What we claim is:

1. A bunch builder for spinning frames including a main builder chain, a bunch builder chain, simultaneously operating means for winding the chains at different speeds, adjustable means for operating said chaln actuating means at a s eed proportioned to that of the spinning rame, a movably supported adjustably mounted roller engaging the bunch builder chain for ad'usting the ength of a bunch, a trip, a re ease adapted to be engaged thereby, and an adjustable operating means connected to the trip for controlling the depth of the bunch.

2. The combination with a counterbalanced bod a worm shaft, awl and ratchet mechanism for operating t e shaft and adjustable means for driving said mechanism from the spinning frame, of a worm gear driven by the worm shaft, driving drums of different diameters revoluble with the gear, a main builder chain and a bunch builder chain connected to and actuated by the respective drums, a pivoted supportin memher, a roller carried thereby and ad ustable thereon for engaging the bunch builder chain, a release, a tri normally engaging the release, and an ad ustable power transmitting connection between one of the drums and the trip for shifting said trip out of engagement with the release.

In testimony that we claim the foregoing as our own, We have hereto aflixed our signatures in the presence of witnesses.
